I have one and it's a great window fan. Really cools down a room. When I went to Walmart to buy a 2nd one recently, they were sold out in store. In for 1!
Don't forget to add a filter. Merv 3

Quote from MikeyJohn View quoted comment :
This is total bs. I purchased 4 of these a month ago from Walmart. All brand new. They each have fallen over once. Each fan broke in various ways. One of them one blade completely came off as a result of it just tipping over onto a rug. The other 3 all run considerably slower than they did for the first week. Others when fell onto the ground shattered the edge frame which broke away. Another one the speed control dial completely came away from the housing. The last description I would label for these fans is un-killable. Instead they are some of the most fragile household products I have ever owned.
I am convinced that Lasko has an army of paid folks out there…..
LOL, no one has paid me.

I gave an honest experience with my Lasko fans, as did you.

It's possible that something has changed in the last year....but 4.5 stars with 48,000 reviews says it's a great product.

is this a popular model for a CR box?

my lasko burnt out every year (I keep it on 24/7)

if you insist on buying this, get the $3 warranty, you will use it

I switched to this brand, it is louder but better quality

These (and all fans) have ZERO cooling capability.
All they do is move air around.

Where in the world are you using these fans that you destroyed 4 of them in a month?

I assume most people put a fans in the windows/doorwalls at night.

Pushing the hot air outside, drawing the cool night air in.

Thus lowering the house temperature an easy 15*f around here.

These are un-killable. Even if they fall down a flight of stairs, the only thing that breaks off is the feet.Back before tariffs/scamflation, these were always $15 for the ACE 4th of July sale - nowadays this is a great priceMade in USA ! Buy it, you won't be sorry.
This used to be true, but the plastic on the new ones is more brittle. I've had one for 15 years that has been through a lot. I bought a second one last year and dropped it getting it out of the box - the plastic guard broke exposing the blades. Really disappointed with how downhill these have gone.

That sucks.

Might be time to try the AeroSpeed @ Menards. $14.99 and a bigger 68w motor

True, but placed in the window, at least at my house, it draws cooler air inside.
